采用PVC介质的三通管挤胀成形数值模拟

摘要

numerical simulation platform of nonlinear explicit finite element analysis software ABAQUAS. Establish to PVC medium three-way tube bulging finite element model, through to which contrast medium bulging and hydro forming results show that the medium bulging of the pipe wall thickness thinning more slowly, the wall thickness distribution is more uniform, and ultimately get larger branch length.%以非线性显式有限元分析软件ABAQUAS为数值模拟平台.建立以PVC为压力介质的三通管胀形的有限元模型,通过对采用介质胀形和内高压胀形的结果对比,表明采用介质胀形可使管件壁厚减薄更缓慢,壁厚分 布更均匀,最终得到更大的支管长度.
